We ran in to a similar problem where we had to set a boolean depending
on whether the element was present or not. To do so, we used a custom
serializer (included below), with the following <value> element:
<value name='confirmed'
usage='optional'
test-method='isValuePresent'
get-method='isValuePresent'
set-method='setvaluePresent'
serializer='EmptyElementSerializer.serialize'
deserializer='EmptyElementSerializer.deserialize' />
public final class EmptyElementSerializer
{
private static final String EMPTY_STRING = "";
private EmptyElementSerializer()
{
}
public static String serialize(boolean b)
{
return b ? EMPTY_STRING : null;
}
public static boolean deserialize(String val)
{
return val != null &&
((val.length() == 0) || Boolean.parseBoolean(val));
}
}
Cheers,
Alex
